Find the length of the hypotenuse of a right triangle where the perpendicular sides are 3 in. And 4in. In length
Answer:
5 inches
Step-by-step explanation:
To find the hypotenuse or any side of a right triangle, use the Pythagorean theorem. This is [tex]a^2+b^2=c^2[/tex] where a and b are the perpendicular sides and c is the hypotenuse. So, plugin 3 and 4 for a and b. This gives 9+16=c^2, which is equal to 25=c^2. Then, take the square of both sides to get c=5.
Another way to solve this is to know the triples. Triples are right triangles that have integers for all of their sides. The triple 3,4,5 is the smallest and most common triple.

A t-shirt increased in price by 1/4. After the increase, it was priced at £65. What was the original price of the t-shirt?
Answer:
52
Step-by-step explanation:
Given:
1/4
Price at 65
Solution:
Let x be the original price
Based on the given conditions, formulate: [tex]x[/tex] ×[tex](1+\frac{1}{4} )=65[/tex]
Apply Multiplicative Distribution Law: [tex]x+\frac{x}{4} =65[/tex]
Multiply both sides of the equation by the common denominator: [tex]x[/tex]×[tex]4+\frac{x X4}{4} =65 X 4[/tex]
Reduce the fraction: x×4+x=65×4
Multiply the monomials: 4x+x=65×4
Combine like terms: 5x= 65×4
Calculate the product or quotient: 5x= 260
Divide both sides of the equation by the coefficient of variable: x = [tex]\frac{260}{5}[/tex]
Calculate the product or quotient: x = 52
get the result: x = 52
Answer: x = 52

"Four is three times the sum of a number and two."
turn this into an equation
Answer:
4=3(n+2) or if you want the unknown variable to be x, then 4=3(x+2)
Step-by-step explanation:
Four is : 4=
3 times the sum : 3(_+_)
sum of a number and two : n+2
4=3(n+2)
Hello! :)
4=3(z+2)
Explanation:
4 is means 4=
3 times the sum of a number and two. There's a hint that tells us that we should multiply 3 by both the number and two, and here's how we indicate that:
3(z+2)
Let our number be z.
The sum of two numbers means we add the numbers together.
So, our equation looks like this:
4=3(z+2)

1428 rounded to the nearest thousandth
Answer:
1428- one is in the thousandth place
the number beside is lower than five so drop it and add zero to the end
1000 -is now your answer
Step-by-step explanation:
hope this helps if not then sorry goodluck and bye
The number 1428 to the nearest thousand is 1000.
When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.
1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Here, the question said the nearest thousand, so I had to look at the value in the hundred places which is 4 and less than 5.
Hence round the number down.
So, 1428 to the nearest thousand is 1000.

what is the slope of (4,1) and (6,-1)
Answer:
slope = -1
Step-by-step explanation:
you subtract the y-values (-1-1=-2) then subtract the x-values (6-4=2) then divide the sum of the y-values by the sum of the x-values
[tex]\frac{-2}{2}[/tex] which simplifies to a slope of -1

the perimeter of rectangle is 2x² + 4x - 4y. its length is (2x - 3y). find the breadth of rectangle
plz help fast plz plz
Perimeter = 2 (l + b)
2x² + 4x - 4y = 2 {(2x - 3y) + b}
2x² + 4x - 4y = (4x - 6y) + 2b
2x² + 4x - 4y - (4x - 6y) = 2b
2x² + 4x - 4y - 4x + 6y = 2b
2x² + 2y = 2b
(2x² + 2y)/2 = b
x² + y = b
Breadth = x² + y

Which of the following is a run on sentence
Answer:
It is defiantly either C or D.
Step-by-step explanation:
It's not A because it has a period with means there is 2 sentences and not 1.
It's not B because it does not have multiple commas.
It might most likely be C because it has the most amount of commas.
If I'm wrong about C, than try D.

I don’t know how to do this problem. Would anyone be able to assist? Thanks!
Answer:
3/2 or 1 1/2 or 1.5
Step-by-step explanation:
first do the equations in each parentheses:
(-5+2) = -3
(-1/2) = -1/2
then multiply both sides:
-3 • -1/2 (which is the same as -3 • -1 over 2)
= 3/2 or 1 1/2 or 1.5

Find the median and mean number of hours for these students.
If necessary, round your answers to the nearest tenth.
Step-by-step explanation:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
so, the mean value is
(10+10+18+18+10+5+12+13)/8 = 96/8 = 12
the median is first not clear when ordering the data set, as we have an even number of elements.
5 10 10 10 12 13 18 18
so, we have to take the mean or average between the 2 middle numbers : 10 and 12.
(10+12)/2 = 22/2 = 11
the median is 11.

Step-by-step explanation:
An art gallery is increasing the asking price of its paintings by 60%. A painting now costs $400.00. How much was the painting before the increase??
$
Answer:
$250
Step-by-step explanation:
The goal here is to find the cost of the painting BEFORE the 60% increase.
To find the cost of the painting, we must take in the information we already have:
Increase percent: 60%
Original price: unknown
Price after increase: $400
$400 is the price of the painting AFTER the increase has been added. So this equals the cost of the painting before the increase, plus the total amount of the increase (which is 60% of the original price).
The total must be (100% + 60% = 160%) 160% of the original painting price.
To find the original price, we must divide the increased price by the new percentage (160%). But how do we get here?
Well, we have 160% and our (fraction) $400/1%. We will have to switch the 160% and the 1%, giving us..
1% $400/160%
We take 400/160, which is 2.5. But this is only 1% of the original price! We want 100%.
So now, we multiply the 2.5 by 100 to get our answer: $250.
